Cat fur colour question
There are rules to cat colour.
I know that, for example, ginger pusses have to be tabbies, alhtough you can breed them sot hat the "tabby" is barely noticeable.. There are two types of 100% white cats. There are genetically 100% white cats, and there are white cats that also have colour genes but aren't being expressed because of a dominant white gene. I think that only girl cats cats can be calicos That "ticking" is a form of tabby marking That the "points" marking is seperate, and so you can have a cat that is only noticable tabby on the points That there is such a thing as "diluted" colour, and a grey cat can well be a genetic black cat that also has the "Diluted" gene, but a grey tabby isn't necessarily one that carried "diluted black" genes. And then tere are the "tipped" cats that can be black on the outside and white (or grey) on the inside, or white on the inside with 'lilac' on the outside etc etc, Or something like that anyway. And looking at IBKFergus, despite him looking black, he definatley has tabby marks in the right light, and his underfur is definatley a lighter colour than his outer fur. So my question is, is there a difference between black tabby and black solid? And does the classic tuxedo kitty have tabby marks in the right light? Yowie |

Genetics would be an interesting study field. MLB |

I can't answer your question, except that I've heard somewhere that
all black cats are really tabbies. Almost all calicos and tortiseshell cats are female. You can get the very rare male calico / tortiseshell, but he will have a genetic defect such that instead of having the normal XY sex-determination chromosomes, he has XXY. It is called kleinfelter's syndrome. I have a question of my own. Spock has a very unusual coat pattern - he is a dark grey tabby on the surface, but if you part his coat, his pattern is only on the very tips of his hair/fur - the bulk of his fur is a light beige / cream colour. Can anyone explain this to me? Is there any such thing as a cat having the "point" gene on all their hair such that the bit of fur that is exposed to cold (the outer edge of fur) turns dark and all the rest is light? For what it's worth, his tail hairs and head hairs are dark all the way to their roots. Tish - who did some genetics *years* ago, but never had a talent for it.

It sounds as if he might be a "smoke" that is, his fur is very pale near
the skin, but each hair has a darker tip. I used to have a chocolate smoke Oriental, he looked as if his coat was watered silk, specially on his head. Marie from OZ "Yowie" wrote in message ...

Your cat would be called a 'silver tabby' , it is the same gene as the
"smoke'. this is distinguished by the pale colour at the root of the hair, and the darker colour at the tip. Marie from OZ "Tish Silberbauer" wrote in message ...

HRFL Tiger is exactly the same - in the right light you can clearly see his tabby-ness, and in his kitten coat which was a muddy brown/black you could actually *see* the faint stripes. It's cause by a rogue gene. Helen M -- Posted via Mailgate.ORG Server - http://www.Mailgate.ORG |

His outer, "cover" fur, is black and his softer underfur is greyish, but you don't see the underfur unless you part the outer fur. Also under direct strong lamplight or sunlight he has definite reddish brown tabby markings. -- Christine in Vantaa, Finland christal63 (at) yahoo (dot) com photos: http://photos.yahoo.com/christal63 |

Some don't seem to. I tried reading a bit about cat colour genetics once, and I decided that if they had used cats instead of pea plants and human eye colour (the simplified version) in basic biology, I never would have passed it. Cat colour genetics are complicated! Cat color genetics make my head explode. :P I've never seen stripes on Stinky's black areas.
